// import * as ed from "https://unpkg.com/@noble/ed25519"; // Unpkg
(async () => {
  // keys, messages & other inputs can be Uint8Arrays or hex strings
  const privKey = ed.utils.randomPrivateKey(); // Secure random private key
  const message = Uint8Array.from([0xab, 0xbc, 0xcd, 0xde]);
  const pubKey = await ed.getPublicKeyAsync(privKey); // Could be set to the contract
})();
